I suspect that the parents did not outlive the daughters in view of the 1861 census. The attached shows that Susan set up a fund/charity to pay for the care of the tomb. Ignore the date, I suspect that this was the date the Charities Commission did some spring cleaning.

This I found on the SEAX website Title:

Someone with more knowledge of C of E workings may be able to add more information, but Bocking was a "Parish Peculiar", in that while it was situated in the Diocese of Chelmsford, it came under the Diocese of Canterbury.
I can find no marriage in either Panfield or Bocking, but as the Rogers girls were born in Pinner, Middlesex, maybe the marriage took place there, but why the reference to Archdeacon of Colchester?
A trip to ERO at Chelmsford on Monday may help with that.
